This is the process where plastic materials are heated, melted and injected into the enclosed mold to product products.


Spray coating/Metalization

1. Air shower: Eliminate dust from the product
2. Base Coating: protect the surface of product and adjust the polishing of product
3. Vacuum metallize: Process to create Al film to metallize the product
4. Top coating: process to protect Al film to enable various coloration work

蒸着,涂漆, 塑料射出物增加金属效果的工序


Put the film on the product and apply heat and pressure to transcribe the pattern non the plastic surface or put ink in the frame with screen and push the rubber panel to print.



This is the process to assemble the product after injection, vacuum metallization and printing.
